Fusion EM®

Energy Management Software

Fusion EM® is the energy management component of Crestron Fusion®. Analyze energy consumption, turn lights on or off, set actions for when a room is occupied, adjust heating/cooling set points, edit demand response settings, and more — all from the web-based interface.

Download Crestron SyncFusion EM® is a complete energy management software solution for organizations of any size. From school districts to corporate enterprises, Fusion EM tracks your organization's carbon footprint while giving you the control to easily change and schedule temperature set points, lighting levels, and demand response settings. Fusion EM even saves you energy by automatically turning off lights and reducing HVAC use in unoccupied spaces.

Complete Control
Fusion EM controls lighting, shades, heating, and cooling for every room in each facility. The rich graphical user interface organizes each room in a hierarchy tree based on building and region—and also features a unified help interface. Users can further customize groups to reflect the logical order of their organization. Change scheduled events such as end of day shut down, edit rules for meeting times, or change climate set points, lighting scenes, and shade levels for the occupied and vacated states in one or more rooms.

In addition, Fusion EM includes a Time Clock calendaring interface with the automation rules that govern how your building operates every day of the year. The result—Fusion EM manages the rules separately from the calendar, simplifying modifications to building operations at the end of the year and during special events.

Energy Tracking
Fusion EM tracks all your lighting loads and provides a bar graph showing real-time and historical energy consumption. For a full picture of how energy is used in a facility, Fusion EM takes advantage of its ability to assess real, measured usage data or simulated energy calculations based on usage information when this data is not available. Click on a group or individual room to view real-time and historical energy usage. View by day, week, month, or year and compare numbers to the previous time period. In addition, renewable energy sources are listed out and displayed so the user can see how much energy has been saved. Project future consumption by simply viewing future periods. Fusion EM estimates energy-use data based on lighting fixture information, or it takes advantage of real data collected by the GLPP, GLPAC, GLS-EM-MCU, and other energy metering devices.

Demand Response Control
Demand response settings call upon predetermined rules that are followed during peak consumption to cut down energy usage by a facility. Fusion EM makes it easy to set these rules. Quickly adjust heating and cooling set points, change the timeout setting for an unoccupied room, and edit maximum brightness of lighting levels. When the demand response mode is activated, Fusion EM ensures that each room’s rules are overridden according to the demand response settings.

Meeting Automation
Fusion EM prepares rooms for meetings,[1] so they are comfortable and ready for business. Adjusting pre-meeting settings is simple with the intuitive GUI. Dropdown menus provide temperature set points and lighting presets — simply make a selection and then choose how many minutes before the meeting you want it to take effect. If the meeting is cancelled, there's no need to tell the room. Once occupancy is undetected after the timeout period, it automatically returns to the vacated state.

Fusion EM reports on historical energy consumption by source and by day, week, month, or year in a way that clearly reveals the peak energy consumption to the space/room and energy category level. Compare data to previous time periods and energy baselines. Crestron Fusion reports enable intelligent data-driven decisions, leading to more effective planning and forecasting. Custom reports may be added upon request.

Global Control
Make global adjustments to every room in your facility with Fusion EM. Choose a group and change the occupied/vacant settings, pre-meeting rules, end of day events, and demand response for the floor, building, or the entire campus.

Furthermore, alarms are sent to the facility manager to alert them of a failure condition, enhancing the way a network is managed.
